  1. I agree, even without any software ajustment. I've done some tests and here are my results (what works for me) : -The sRGB function in Color Transform is unusable, it crushes the blacks too much. -From BT1886 to sRGB : a 2.4 to 2.2 correction is not necessary. A computer screen shows the original 1/2.4 gamma a bit brighter, which is nice in a bright environment. -From BT1866 to DCP : a 2.4 to 2.6 correction is not wanted, as i want the DCP to be darker in theater. For a fast delivery, i will only do the Rec709 to XYZ transform, but i really think that a trim pass is needed or at least a proper "Output Device Transform" in ACES.
  2. Yes, i'm sure it's better to do a trim pass manually to make those deliverables. But is there a way to do it automatically ?
  3. Hi, i've got few questions about gamma correction. I have the feeling that i could be totally wrong 1- In Resolve (for example), when we set the working space at 2.4 gamma, this means that the signal is actually a power of 1/2.4, right ? We're working on the inverse function, because the monitor is doing "the real" gamma correction at ^2.4 So in scopes, what we are seeing is also the signal with a 1/2.4=0.42 gamma !? Can you confirm that ? 2- Do we need to make a gamma compensation when exporting a sRGB file from a BT1886 master ? If i understand it correctly, gammas are here (at least at the end of the pipeline) to compensate the differents viewing environments. sRGB is made for a bright environment, so the image should be brighter than BT1886, isn't it ? Then : - If i just play the BT1886 master (roughly gamma 1/2.4) on a computer, the monitor applies a gamma correction of 2.2 : the image is brighter but appears ok because there is a lot of surrounding light. - If i export my master with a color transformation node from 2.4 to 2.2, the image should be the same on the computer than on my reference monitor, but appears too dark in the bright environment. What should i do ?
